You can learn to do this independently or get a rockstar REALTOR to lead the way.

A well qualified business broker or someone else experienced in those calculations (think someone with statistics/finance expertise) can easily do this.  

Perhaps it has something to do with the statistical average where in Australia, if you are borrowing 75% on property in the cities or suburbs, it is almost impossible to get positive cash flow ANYWHERE, whereas BP subscribers are aware that in MANY parts of the USA, the opposite is true.

Independent of the agreement instructions, regardless if its a title company or brokerage who is serving as the escrow agent, its rare for the deposit to be released without a mutual sign off or court order because there are disputed facts.

I never go off of a flat percentage on anything, I analyze the costs to get to a specific return I target and analyze the risk that is involved. 70% may be an initial metric to see if it is even worth pursuing, but every deal should be evaluated independently based on costs, time and risk involved.

A broker who can also deliver a reputable management company (themselves or an independent company) willing to take over management at closing is a real plus for any residential rental investment. 

My goal of course, is financial independence as soon as possible. 

Well, those properties will statistically attract corresponding Class B & C tenants.So, how should an investor account for Tenant Payment Performance/ DEFAULT in their analysis? 

Statistically speaking. 

Nevermind the unlikelihood that any ONE of them is appearing in the top 10 that often (especially at the rate we're getting bookings, I know we're not showing up on the 1st page nearly that often), it's statistically impossible for 30 listings to show up in the top ten 50% of the time even if our 30 listings were the only ones in the entire market, instead of there being 20,000 other listings.It makes no sense.
